+    @descr  It try to close the given resource first.
+            Delegating of the ownership can be influenced from
+            outside. If closing isn't possible (because the
+            needed interface isn't available) dispose() is tried instead.
+            All possible exceptions are handled inside.
+            So the user of this method has to look for the return value only.
+
+    @attention  The given resource will not be cleared.
+                But later using of it can produce an exception!
+
+    @param  xResource
+            the object, which should be closed here.
+
